Abstract: 1,264,687. Coating cut edges of woven fabrics. DEERING MILLIKEN RESEARCH CORP. 12 Aug., 1969, No. 40341/69. Heading B2E. The roughness of a cut edge on a woven fabric is reduced by heating the cut edge, coating it with a film forming polymer and treating the polymer to solidify it on the coated edge. The fabric may be on a strip used to stitch in the waists of trousers or skirts to prevent curling of the garment when worn and may have been produced by slitting in the warp direction a fabric woven with a cotton warp and nylon fill. Both edges of the strip may be heated and coated. The polymer may be applied in the form of an organosol, plastisol, hot melt, aqueous or organic solvent solution or emulsion or polymeric syrup and may comprise a polyamide, polyethylene or copolymer thereof with polyvinyl acetate, polyacrylic, polyvinyl chloride or a copolymer thereof, polyvinyl acetate or a copolymer thereof, acrylonitrile/butadiene or styrene/butadiene copolymer, polyurethane, carboxylated acrylic copolymer, polyvinyl alcohol, polyacrylate, polyester or epoxy resin. The cut edge of the fabric may be heated prior to coating to at least 150‹F. After coating the polymer may be solidified by heating at 325‹-375‹F. In Fig. 2 fabric 10 is fed from roll 18 to heating oven 20 where the edges or the whole fabric are heated and is passed through coaters 22 which apply film forming polymer to both edges of the fabric by means of rolls 24 and 26 which rotate in baths 28. The fabric is then passed through second heater 30 to cure the polymer and is taken up on roll 12 driven by surface drive roll 32 although second heater 30 may be dispensed with if the residual heat in the fabric is sufficient to effect curing.

Abstract: 1295640 Transistor bistable circuits PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 5 Dec 1969 [10 Dec 1968 30 Oct 1969] 59523/69 Heading H3T The outputs M, M of a master flip-flop T4, T5 are connected to a slave flip-flop T12, T14 through respective gates T9, T8, T11 and T17, T18, T15, each including a parallel pair of transistors such as T9, T8 one receiving the master output and the other a clock pulse; and the outputs Q, Q of the slave are connected to the master through respective gates T2, T1 and T6, T1 each including a series pair of transistors, one receiving the slave output and the other the clock. Alternatively the parallel and series pairs of transistors may be used respectively in the gates receiving the slave and master outputs (Fig. 4, not shown), the parallel pairs (31, 32 and 51, 36) being in this case in series with the flip-flop transistors (34, 35). F.E.T.'s are used and their channel length to width ratios are selected in relation to one another and to those of the resistor-connected F.E.T.'s in the drain circuits, to prevent erroneous operation. In operation, when a clock pulse (negative) T occurs, T1 conducts and enables the master T4 T5 to be set by the Q Q signals, the same clock pulse T holds T8 and T18 on so that T11, T15 are held off and the slave state is not affected. At the end of the clock pulse T, whichever of T17, T9 is not held on by the M, M signals, will go off and permit the associated one of T11, T15 to conduct to reset the slave. Thus the master is set by conduction of a gating F.E.T. and the slave by non-conduction of a gating F.E.T.; this is said to reduce dissipation, reduce the number of gates, and shorten interconnections while avoiding cross-connections between master and slave, to facilitate integration. Junction transistors are mentioned.

As shown, the gate 28 is disposed higher than the accumulator 20 and also higher than the conduit system of the freezer evaporator 19 arranged between the accumulator 20 and the gate 28. The capillary tube 14 is introduced into the evaporator 18 at the highest location thereof, so that the refrigerant flows downwardly in the tube coil 17. In operation, upon de-energizing the compressor 11, under the control of thermostat 37, the forced circulation of the refrigerant is interrupted. The liquid, warm refrigerant flows from the capillary tube 14 into the cooler evaporator 18 where it evaporates; the vapour pressure so formed forces the column of liquid refrigerant accumulating at 23 from the evaporator 18 and over the barrier 28.

Abstract: 1315969 Removing cyanide ions from solutions of cobalt corrinoids GLAXO LABORATORIES Ltd 30 Nov 1970 [1 Dec 1969] 58631/69 Heading C2V Free cyanide ions occurring in alkaline solutions of cobalt (I) corrinoids formed by reduction of corresponding cyanocobalticorrinoids, are removed by cyanide-complexing agents provided in the alkaline solutions, so that the cyanide ions are incorporated in the complexes and are no longer able to interfere in subsequent reactions of the cobalt (I) corrinoid. The complexing agent may be a cupric or ferrous salt and the reduction may be effected by sodium, potassium or lithium borohydride or by a chromous salt or zinc and acetic acid or hydrogen in the presence of a catalyst. The cobalt (I) corrinoid subsequently may be reacted with an alkylating, acylating or sulphonylating reagent whereby an alkyl, acyl or sulphonyl cobalticorrinoid is formed. In examples cyanocobalamin is reduced with sodium borohydride and the cyanide ions are removed by forming complexes with ferrous sulphate and cupric chloride, the products then being reacted with tosyl adenosine to form vitamin B 12  coenzyme and with methyl toluene-p-sulphonate to obtain methylcobalamin.
